9.2.2 Apple Macintosh Workstation
System Requirements:
•
Mac OS X 10.3.7 or greater
•
FireWire 400 Port
•
CPU: PowerPC G4 or G5 @ 700MHz or greater
(G4 @ 1.2GHz recommended for high sample rates)
•
Memory: 256MB RAM or greater
•
Display / Colours: 800x600 @ 65,536 colours or greater
The installation CD-ROM is not required for Macintosh applications. The Operating System
will automatically detect any connected ADA-8 device and make it available to applications.
9.3 Fitting the Module
In most cases, the module has been factory-fitted so, unless you are fitting the module
yourself, the remainder of this section may be ignored.
The FireWire I/O Module can be fitted to either Digital I/O Slot (DIO1 or DIO2) in the rear of
the ADA-8 (as shown in the Layout section of the Operation Manual).
Where an ADA-8 is to be fitted for 16-channel AD, 16-channel DA, or 8-channel AD/DA at
176.4kHz and 192kHz sampling rates, operation FireWire I/O Modules must be fitted to BOTH
DIO slots.
For details of how to fit the Module, refer to the Adjustments and Upgrades section of the
Operation Manual.
9.4 Connection
The FireWire I/O Module has two six-pin FireWire sockets for connection to the bus. The
module may only be connected to FireWire 400 (1394a) buses. The module does NOT
support direct connection to FireWire 800 (1394b) buses.
The module does not require FireWire bus power in order to operate and so may be
connected, using the appropriate lead, to the four-pin FireWire connector type often found on
notebook computers. When connected to a six-pin, power providing, FireWire interface the
module passes power straight through to the next device on the bus.
In a single ADA-8 application simply connect a FireWire cable between the workstation and
either of the module’s six-pin sockets. In most cases you will require a six-pin to six-pin
FireWire cable (for desktop computers), or a four-pin to six-pin cable (for notebook
computers).
Additional ADA-8 units may be added to the bus, by connecting a six-pin to six-pin cable
between the unused socket on the first unit to either of the sockets on the next unit.
Do NOT connect a cable back to the workstation from the last unit in the chain, as this will
create a loop, which will stop the FireWire bus from operating correctly.
In the case that two FireWire I/O Modules are fitted to the same ADA-8, the modules must be
connected together externally using a six-pin to six-pin cable.
